General Guidelines and Warnings

• Minimum permeate flow for individual elements can be 20 percent below the listed flow.
• Elements are vacuum sealed in a polyethylene bag containing less than 1.0% sodium meta-bisulfite.
• Permeate obtained from the first hour of operation should be discarded.
• Avoid static permeate-side backpressure at all times.
• These membranes may be subject to drinking water application restrictions in some countries; please check the application status before use and sale.
• For element loading, use only glycerine to lubricate O-rings and brine seal.
• The customer is fully responsible for the effects of incompatible chemicals on elements. The presence of free chlorine and other oxidizing agents will cause membrane failure, and such damage is not covered under warranty.
